Abstract: Version management of models is common for structural
diagrams such as class diagrams but still challenging for
behavioral models such as process models. For process models,
conflicts of change operations are difficult to resolve because
often dependencies to other change operations exist. As a
consequence, conflicts and dependencies between change operations
must be computed and shown to the user who can then take them into
account while creating a consolidated version. In this paper, we
introduce the concepts of dependencies and conflicts of change
operations for process models and provide a method how to compute
them. We then discuss different possibilities for resolving
conflicts. Using our approach it is possible to enable version
management of process models with minimal manual intervention of
the user.
